Because all of the taxidermist Ive talked to in PA told me that you cant really make a living if you dont charge the money and that anything under $400 is too cheap
The form costs about $30
Tan the skin about $30
glue, eyes and other stuff $20
Skin / prep the cape 2 hours
Mount deer 8 hours
You do the math
Neither the price or the time you wait have anything to do with the quality of the mount. Even when you wait for a year - that cape is sitting in a box for 11 months.
The quality comes from skill and pride - and IMO that is worth every penny you pay.
